Even when troubleshooted it strongly drains volume and over exaggerates the effect.

I use this on the back end of an arturia minibrute analog synthesizer, and get all manner of incredible feedback sound effects when I crank up the "intensity" knob and start dialing around the "repeat rate" knob on the pedal.

Great sound effect.

Very cool effect at truly nice price.

I wish the delay was longer, but I can still get some nice effects and the price is worth it.

awesome delay effects for great price....

Nice effect, but too much noise even with a battery
